Certain example embodiments relate to white-box testing techniques, e.g., for graphical user interfaces (GUIs). Responsive to a first parameter received from a test suite executer, test bootstrap code included in an application is executed, where the application and the test suite executer run in the same browser. A test case to be run on the application and a test case executer to execute the test case are retrieved by the executed test bootstrap code. The retrieved test case is executed in a same context of the browser as the application. Results from executing the test case are stored.
